The utility model discloses a thyristor trigger module, comprising a second trigger circuit and a first trigger circuit used for triggering a forward thyristor and a reverse thyristor respectively. The second trigger circuit comprises a second voltage sampling circuit electrically connected between a forward anode connecting terminal and a reverse anode connecting terminal and in series connection with a second diode, and a second trigger electrode limited current circuit electrically connected between a sampling point of the second voltage sampling circuit and a forward trigger electrode connecting terminal. The second trigger electrode limited current circuit is in series connection with at least one second high voltage trigger diode, and the first trigger circuit can possess a structure symmetrical with the first trigger circuit. The thyristor trigger module of the utility model is simple in structure and strong in universality, can utilize a universal structure to manufacture the modules of different secu
